Abstract: PURPOSE:To obtain a homogeneous recording medium excellent in flatness, by accommodating the product of electric power density to be applied to a specific metallic target and the average stay time of dissociation gas for including H (hydrogen) in an optical information recording film as a constituent in a discharge space within a specific range. CONSTITUTION:One of Te, Sb and Ag is fitted to the lower surface of a power applying terminal 5 in a vacuum case 1 as a target 4 and a substrate consisting of glass or transparent plastic is set up on an opposed holder 6. Air in the case is exhausted from an exhaust port 2 and hydrocarbon such as CH4 or gas such as NH3 which can dissociate H by plasma sputtering is fed from a gas guiding port 3 with about 10<-3>-10<-2>Torr. Inert gas such as Ar and N2 is fed together with the dissociation gas so that the partial pressure of the dissociation gas is higher than that of the inert gas. The process is controlled so that the recording film is formed in the range setting up the product of the electric power density to be applied to the target metal and the average stay time of the dissociation gas in the discharge space to 0.05Wsec/cm<2>-0.5Wsec/cm<2>. Thus, the recording medium comparatively high and uniform in stacking speed and superior in recording and reproducing characteristics is obtained.

Title: Method of measuring length
Inventor: KISHIZAKI AKIRA
IPC: G01B21/06
Filed: 1982-09-13
Abstract: PURPOSE:To measure the length of the material to be measured by use of the final value of a counter, a time from the point where the rear end of the material to be measured has passed a first width gauge to the point where a second width gauge starts detection, and a time required for the rear end to pass the second width gauge. CONSTITUTION:Since the distance between first and second width gauges 2, 3 is L0, the position of a material 1 to be measured at the point where the width gauge 3 first detects the width W1 corresponds to a position spaced from the leading end by L0. Subsequently, the difference between the every adjacent detection positions is given by an equal interval of L0 likewise until W2, W3... Wn. Accordingly, multiplication of the final counter value (n-1) by L0 gives a length DELTAL from the leading end to the position of the width Wn shown in the equation (1). Also, a time t1 from the point where the rear end has passed the width gauge 2 to the point where the width gauge 3 starts detection of the part of the width Wn is measured. Further, a time t2 required for the rear end to pass the width gauge 3 is measured. By so doing, a length from the part of the width Wn to the rear end can be obtained using the equation (2). Thus, by finally making calculation shown in the equation (3) in a measuring device 4, it is possible to measure the overall length of the material 1 to be measured.
